WHAT DOES 3030, 4040 AND (1010), (121) MEAN IN THE BREATH PROTOCOLS?
In our Step Up Breath Protocol, you will see numbers like 3030, 4040, 5050 indicated.
These numbers are seconds. The first number is the inhale, the second and last numbers relate to hold time and the third number is the exhale. A 3030 protocol employs a 3-sec inhale and 3-sec exhale. No holds.
When you see something like Cadence 1a (1010) or Apnea 1 (121) these numbers refer to ratios based on your CO2 Tolerance Breath Test and indicate inhale, hold and exhale times. For instance, an Apnea 1 (121) for a person with a 40-sec CO2 Tolerance breath test time would correspond with a 4-sec inhale, an 8-sec inhale hold and a 4-sec exhale. These numbers are determined using the Breath Test Calculator.
